Abstract - This paper describes the use of Hardware-in-Loop
(HIL) simulation and Rapid Control Prototyping (RCP) tools for
the accelerated design and optimization of battery management
systems (BMS) typically found in hybrid/electric vehicles. The
BMS is an electronic system that manages a rechargeable battery
pack. Its functions include monitoring the cell/pack voltage,
current, temperature, state-of-charge, depth-of-discharge, and
state-of-health. Besides reporting this data to a supervisory
(powertrain) controller, the BMS protects the battery by
preventing it from operating outside its safe operating range and
balancing the individual cells. Programming, testing and
validation of the BMS with real batteries is a time-consuming,
expensive and potentially dangerous operation since physical
batteries needs to be discharged and re-charged for every
development iteration. With the help of virtual batteries models
as part of a HIL simulation, the BMS algorithm can be
developed, calibrated and validated in a very secure and timeefficient
manner resulting in a significant product development
time reduction.
